This video details the process of repairing pitting in older shotgun barrels using a Sunnen honing tool. It emphasizes the importance of measuring choke depth to prevent damage and outlines a step-by-step abrasive progression, starting with 80-grit stones and moving to finer grits like 150-grit. Proper tool adjustment and lubrication are crucial for effective polishing and maintaining barrel integrity.

This video visually explains firearm pitting, distinguishing it from surface rust. Pitting occurs when rust eats into metal, creating permanent divots even after the rust is removed. The demonstration uses a bayonet sheath to show how pitting appears on external surfaces and inside rifle bores, contrasting it with a clean, polished finish.
